A lecture on basic aspects and application of Erlang was delivered by J.P. Mathews on the 14th of August'2009 at the Ilug-CalInfo meeting.

Erlang is a functional programming language with nice features for making simultaneous use of multiple CPU cores. The language itself may be seen as an extension of PROLOG.

You can have an idea about some of Erlang's features and its application domain from JPM's presentation.
